587091 divided by 80 
We're looking to find how many times 80 goes into 587091.

Let's proceed to step 1:
80 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 80

Step 2:
When dividing 58 by 80, we get 0 with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Fetch the next digit (7) from the dividend, attach it to 58 and continue: 587 / 80

Step 3:
If we divide 587 by 80, we get 7 and a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 560 from 587 and we're left with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 80

Moving on to step 4:
When dividing 270 by 80, we get 3 with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
The remainder is 30 after subtracting 240 from 270.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 80

Step 5:
If we divide 309 by 80, we get 3 and a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 733.0
If we subtract 240 from 309, we get 69.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 80

On to step 6:
80 goes into 691 8 times with a remainder of 51.
Record the quotient 8 as the next digit in the result. 
Result so far: 7338.0
Deduct 640 from 691 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
If we divide 510 by 80, we get 6 and a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 7338.6
Subtracting 480 from 510 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
When dividing 300 by 80, we get 3 with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 7338.63
If we take 240 away from 300, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 7338.637
Subtracting 560 from 600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 7338.6375
Subtracting 400 from 400 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7338.6375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 7338.6375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 7338.6375, and the remainder is 0.0.
